Why is a shared calendar not syncing?

Question

Hello

I have followed MS guidance to share my MS365 calendar with my partner who has an Outlook.com account.

While he was able to open the calendar in his account, it is a snap shot and not updated.

Other guidance says to share a URL with him, but I cannot work out how to share a URL from my MS365 account, neither in Outlook for Desktop nor Outlook for browser.

Does anyone know how to do this?

BTW - there is also guidance to stop caching my mailbox, that didn't create the sync we need, but it did stop my groups loading.

Many thanks

Hi Perplexed user99,

Thank you for posting on Microsoft Forum.  

Please request the user1 remove and re-share the calendar with the appropriate permission with user2. When user2 receives the calendar sharing notification email, click the button "Accept and view calendar" in the notification email, which will add the shared calendar to his/her calendar list, and then try again to see if he can create new meetings or modify existing appointments on the shared calendar.

Can you ensure that it is not related to permissions? If so, please verify which permissions were given Share calendars with external users - Microsoft 365 admin | Microsoft Docs.

Let's suppose the user you're sharing with receives an email notifying him that the calendar has been shared with them and contains a link to it. When user click the link, an .ics file is downloaded; when user double-click the.ics file, a shared calendar is added to the computer's outlook. After this, the items are synced with the main calendar.

If you have any further concern on this issue, feel free to let me know. Looking forward to hearing from you.

Best Regards,

De Paul

Hello De Paul

It now works!!

My settings were all correct. I think the difference was creating the share from Outlook for browser rather than Outlook desktop app. I have a similar issue managing groups, which is fairly disappointing given the cost of the desktop apps.

But thank you.
